Abstract

PURPOSE:To prevent the repetition of the same error by storing the erroneous number in a telephone set when erroneous dialing is performed and urging a caller to confirm when stored number is retrieved at the time of dialing. CONSTITUTION:At the time of trunk line dialing, whether or not the number detected in a dial detection part 11 is recorded in the memory of a telephone set control part 14 is retrieved and when recording as the erroneous number is present, alarm is issued by a speaker 18 and a display 17 and the input of a confirmation key 103 is urged. When the input is detected in a key input detection part 12, the number is transmitted through a line interface 13. When the confirmation as the erroneous number is performed the key 103 is not pushed, on-hooking is performed and redialing is performed without calling the number. Also, when the key 103 is pushed and the call is originated in spite of the alarm, the number is deleted from the memory for recording the erroneous numbers of the control part 14. Then, from the next time, dialing is performed without the push of the key 103.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for preventing the reoccurrence of an erroneous telephone due to an erroneous dialing of a telephone which makes a call to a public telephone exchange (or private telephone exchange) by dial operation (rotary dial or key input).

[0002]

2. Description of the Related Art A conventional telephone in which a dialed number is directly sent to an exchange cannot prevent erroneous dialing. Also, some multifunction phones with display devices
One-touch dial that displays dialed numbers and sends the dial to the exchange after confirmation by the user (Method 1), or dials the registered dial just by pressing a specific key. (Method 2), etc.

In addition, as a known technique, Japanese Patent Laid-Open No. 2-168
There is a method like 51 (method 3). In this method, the telephone is provided with a display for confirming the input dial at the time of making a call, a display for confirming the call, and a call confirmation key. Always prompt the caller to press the confirm key before sending the digit to the line. The numbers called by pressing the confirmation key once are recorded as a list on the telephone. When a user tries to make a new call, the dial input is always compared with the list recorded in the telephone, and if the number is included in the list, it is regarded as the correct number without pressing the confirmation key. The call is made. This makes it necessary to confirm the user when making a call to a party who has never called before.
It is possible to suppress the occurrence of wrong phone calls.

[0004]

In method 1, the caller must always check the caller number every time a call is made, and if the caller has a long phone number, a wrong call may occur due to oversight. In addition, even if the caller remembers the wrong phone number and makes a mistake, there is a possibility that the same caller may repeat the wrong call.

In the method 2, the operability is poor unless the user knows which telephone number is set for which key, so the number of keys is limited to some extent. For this reason, there is still a possibility that a wrong call may be made to the other party who cannot be registered in the key.

[0006] In method 3, although it is possible to suppress an erroneous call for the time being, it is necessary to record the correct call destinations as a list, so in many cases an unspecified number of callers are called. Need memory. Also,
When making a call to a number that is not on the list, the operation is complicated because the call is always confirmed. In addition, if the user does not notice the mistake when confirming the call or if the caller has mistakenly stored the caller's number, the wrong number will be recorded as the correct number once the call is made. May make repeated false calls after that.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and when a user of a telephone makes a call to a callee and then finds an error, the call at that time is sent. When it is found that the wrong phone registration means for registering the wrong number as the wrong phone number and the phone number entered when making a new call match the number registered in the wrong phone registration means, the user And a warning means for confirming the call origination.

Further, the warning means provides a telephone which collates with the number in the wrong telephone registration means every time a telephone number is inputted by one digit at the time of calling.

Further, when the user inputs the number registered in the wrong telephone registration means and makes a call, a telephone having a call confirmation key for canceling the warning and deleting the number from the wrong telephone registration means is provided. To do.

[0010]

In this method, when a wrong call is made once, the wrong telephone number is stored in the telephone as a list. When making a call, the dialed telephone number is searched for in the list, and if it is included in the list, the caller is prompted to confirm whether or not the call is really made. This prevents the same person from repeatedly making a wrong call.

Regarding dial input at the time of making a call, every time one digit is input, it is searched whether the number dialed up to that point is in the list. A warning is issued when an incorrect digit is entered on the way, so that the wrong phone call can be noticed before the subsequent invalid digit is entered.

Further, even if the wrong number is registered once, if the outgoing call is confirmed once and then the outgoing call is made, the number is deleted from the list. It becomes unnecessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic configuration of the present invention is shown in FIGS.

In FIG. 1, 10 is a hook detection device, 11 is a dial detection unit, 12 is a key input detection unit, 13 is a line interface, 14 is a telephone control unit, 15 is a voice bus, 1
6 is a receiver interface, 17 is a display, 1
Reference numeral 8 is a speaker, 19 is a tone generator, 101 is a function key group, 102 is a registration key, and 103 is a confirmation key. FIG. 2 shows the internal configuration of the telephone control unit 14 of FIG. 1, 20 is a main control unit, 21 is a calling number recording memory, 22 is a data update executing unit, 23 is an incorrect number recording memory, and 24 is Represents a number search execution unit.

In this system, the number search execution unit 24 searches the digit number detection unit 24 to determine whether or not the digit string detected by the dial detection unit 11 when the user originates the station line is recorded in the error number recording memory 23. If it is registered as a wrong number, a warning is given through the speaker 18 and the display 17, and the user is prompted to enter the confirmation key 103. When the input of the confirmation key 103 is detected by the key input detection unit 12, a digit is sent to the line through the line interface 13. When the user recognizes that the wrong number has been dialed, the user can redial without calling the wrong number by going on hook without pressing the confirmation key 103. When the confirmation key 103 is pressed to make a call, the number at that time is deleted from the error number recording memory 23 by the data update execution unit 22. As a result, even at the call destination registered as the wrong number before, if the user makes a call with the consent, the call can be made from the next time without pressing the confirmation key 103.

To update the list of wrong numbers, the user inputs the registration key 102 after the start of the call and the key input detection unit 1
2 will be accepted. This state is maintained until the call ends and the user goes off-hook for the next call. By pressing the registration key 102 from the time when the user notices that he / she made a wrong call after starting the call to the time when he / she ends the call and goes off-hook for the next call, the call destination at that time (or immediately before that) Is registered in the wrong number recording memory 23.

FIG. 3 is a list format in the error number recording memory 23, in which a certain number of telephone numbers registered by the user of this telephone as an error telephone number have been recorded, and the most recently registered number. The items are arranged in the order of registration, starting from the first one. The access to this list is performed by the data update execution unit 22 of FIG. 2, and the number data recorded in the transmission number recording memory 21 can be registered / deleted with respect to the list. If the list is full at the time of registration, the oldest registered number (bottom of the list) in the list is automatically deleted and new data is recorded.
